To solve this problem, let's break down the pizza's slices and calculate the total fraction of the pizza they represent, and then determine for which values of $n > 1$ the pizza can be divided equally.

Step 1: Break Down the Slices

The problem mentions four types of slices with no explicit fractions given for some of them. Let's use variables to represent the unknowns for now. We have:

• Two slices are each $\frac{a}{b}$ of the whole pizza.
• Two slices are each $\frac{c}{d}$ of the whole pizza.
• Four slices are each $\frac{e}{f}$ of the whole pizza.
• Two slices are each $\frac{g}{h}$ of the whole pizza.

Step 2: Total Fraction of the Pizza

The total pizza is 1 whole pizza. Therefore, the sum of all slices should equal 1. The total fraction of the pizza is given by:

$2 \times \frac{a}{b} + 2 \times \frac{c}{d} + 4 \times \frac{e}{f} + 2 \times \frac{g}{h} = 1$

Step 3: Conditions for Equal Distribution

We need to find the values of $n > 1$ for which each of the $n$ friends can receive an equal share of the pizza without cutting any slices. This means that the total fraction each person gets is $\frac{1}{n}$, and each person must receive a combination of slices that sums to $\frac{1}{n}$.

The key to solving this is finding the values of $n$ such that the total fraction 1 can be divided evenly into $n$ equal parts, each part being $\frac{1}{n}$.
